Vedclass · Answer

(C) $1-$propanol is a primary alcohol $(CH_3CH_2CH_2OH)$,which on oxidation with hot $Cu$ gives an aldehyde (propanal,$CH_3CH_2CHO$).$2-$propanol is a secondary alcohol $(CH_3CH(OH)CH_3)$,which on oxidation with hot $Cu$ gives a ketone (acetone,$CH_3COCH_3$).Aldehydes give a positive test with Fehling's solution (red precipitate),whereas ketones do not.Therefore,heating with $Cu$ followed by treatment with Fehling's solution distinguishes the two.

Which of the following processes can be used to distinguish between $1-$propanol and $2-$propanol?
